Used when some geek delves too far into a technical explanation. to some girl on MSN or AIM.

Geek: "Hey my webcam isn't working, sorry. I could explain why but won't"
Girl: "Okay"
Geek: "Lol, I took it appart to make it into an infrared cam. It's pretty easy you just cut a bit of film negative up and put it inside, taking the old filter out. Means it see's infrared light instead of visible, cause the film negs blank that out. It's pretty cool I'm wearing a black shirt and it shows up white on the camera."
Girl: "tl;dr"
